Robert Dale Owen himself was an Atheist formerly, and a very zealous and able advocate of Atheistical views. He gives his articles in the Atlantic Monthly as an autobiography, and seeks to make the impression that he has revealed to his readers all the important facts of his history without reserve. And he has certainly revealed some strange things. But there are certain facts which he has _not_ revealed, facts of great importance too, calculated to show the demoralizing tendency of infidelity. We propose to render the autobiography of Mr. Dale Owen more complete, more interesting, and more instructive, by the addition of some of those facts. Frances or Fanny Wright was a friend of Mr. Dale Owen's. She was the great representative female Atheist of her time. Like Mr. Dale Owen's father, she was rich, and like him, seemed desirous to do something in the way of philanthropy. Mr. Dale Owen, who was her agent for some time, gives us some interesting facts with regard to her history, which may prove of service to our readers. In Buckle we have an Atheistical Historian, who endeavors to prove that we are indebted for all the advantages of our superior civilization, not to Christianity, but to natural science and skepticism alone. He represents Christianity as the enemy of science, and as the great impediment to the advance of civilization. These views of Buckle we regard as false and foolish to the last extreme, and we expect to be able to show that Europe and America are indebted for their superior civilization, and even for their rich treasures of natural science, _not_ to infidelity, but to the influence of Christianity. Matthew Arnold has just published an interesting book entitled LITERATURE AND DOGMA. It is however a mixed work; and we propose, while noticing a number of its beautiful utterances, to make a few remarks on some of its objectionable sentiments. There is a great multitude of important facts with regard to Christianity,--facts which can be understood and appreciated by persons of ordinary capacity, and which no man of intelligence and candor will be disposed to call in question; yet facts of such a character as cannot fail, when duly considered, to leave the impression on men's minds, that Christianity is the perfection of all wisdom and goodness, and worthy of acceptance as a revelation from an all-perfect God, and as the mightiest and most beneficent friend of mankind. A number of those facts we propose to give in our next volume. MODERN SKEPTICISM. CHAPTER I. INTRODUCTION. When a man has travelled far, and seen strange lands, and dwelt among strange peoples, and encountered unusual dangers, it is natural, on his return home, that he should feel disposed to communicate to his family and friends some of the incidents of his travels, and some of the discoveries which he may have made on his way.
